[I can offer no explanation of the discrepancy in time of 

 appearance. — Edward Newman.'] 



Larvce of Boinby.v Pernyi. — These larvas manifest some 

 disposition to attack each other when in confinement, — a 

 circnmstance rather unfavourable to attempts to breed the 

 species on a large scale, with a view to an economic use of 

 the cocoons. The time of inactivity during the ecdyses is 

 remarkable, in the case of some individuals, extending occa- 

 sionally to seven days. It is compensated for by brisk 

 jaw-work afterwards; for, through the latter part of their life, 

 these larvai seem to eat both by day and night. On the day 

 before the cocoon is commenced they discharge from the 

 mouth a good quantity of fluid, which is not, however, of an 

 acrid character, but rather glutinous. It is sometimes emitted 

 in less quantity, at an earlier period, if a larva is irritated. 

 —J. R. S. Clifford. 



[Notwithstanding my earnest desire to promote the science 

 (if I may so call it) of Economic Entomology, I would venture 

 to caution entomologists against attempting to rear the various 

 Asiatic silkworms, which have verticillate larvae and pyriform 

 cocoons, on too extensive a scale: it is well to be certain that 

 you are able to walk safely before you attempt to run. I have 

 become cognizant of such repeated failures in the attempts to 

 rear these silkworms that it seems needful to offer this 

 caution. No sufficient cause for the mortality among these 

 magnificent larvae has yet been discovered. Such cause 

 must not only be discovered, but removed, before extensive 

 operations can be successful. — Edward Newman.] 



Fidonia atomaria. — On Sunday, October the Ilth, while 

 walking through Sherwood Forest, an insect flew across the 

 path, which 1 took to be Cheimatobia brumata; but as I had 

 not taken that species here I netted it to make certain, when 

 it proved to be a male specimen of Fidonia atomaria. Is not 

 that unusually late for this species to be on the wing? —

Eupithecia K/ianiiaia of Gregson. — Seeing Mr. Gregson's 

 description in the 'Entomologist' (Entom. vii. 255) of a pug 

 new to science (E. Knauliata), it may not be out of place to 

 remark that I have known the locality where it is taken ever 

 since I was a schoolboy, and remember, when birds-nesting 

 on Bullshill, that heath grew there in abundance ; and at a
